4l80 swap what yoke?

[dickwiley]

i just know since it has that o-ring on it that the yoke has to slip over it and it seals the yoke so that the trans fluid doesnt get in the splines. I dont have a lot of cash left for my swap so im tryin to make sure i dont buy the wrong thing and spend money i dont need to spend.

The o ring is not needed unless your using a bolt on yolk the new trans yolk will be sealed on the end instead of having a bolt hole.

[dickwiley]

I figured id keep it bolt on since thats the way it came and i dont wanna deal with spline issues and what not.

[jansen]

Then your gonna have to have a stub and a slip yolk put in your factory shaft to make that work. The driveshaft has to have some travel in it somewhere. I work at a driveshaft shop, we build them all day every day.

[dickwiley]

So you recommend me cut the oring off and just use a slip yoke. I just figured since this is goin back in a truck I wouldn't need a slip yoke since it came with a bolt on yoke. So if you have what im needing would you be willing to ship me one. I really want something I can put on bolt up and go. No cutting modifying or anything. Dont want yoke tailshaft spline issues. Did you see the picture I posted of my tailshaft? The oring is different kinda flat and not easy to remove.

[jansen]

O ring is flat because its wore out. I'd be glad to help you. Is your shaft a 1 piece shaft or a 2 piece?

[dickwiley]

Lol I have no idea to be honest. How do I find that out. Its been since high school since I've even messed with a transmission

[kewljay223]

just look at it. one piece is one long shaft with two u-joints and a yoke on one end... a two piece has another joint in the middle with a carrier bearing. the carrier bearing will have its own crossmember under the truck to sit on.

so you know what it looks like, this is my two piece after i picked it up from the shop after my 80e swap. had the long full splined yoke and shortened 2 inches, all new joints and bearing.

[dickwiley]

Oooooh I thought he meant tailshaft lol not drive shaft. Yes its a one piece drive shaft. I feel dumb right now. He said shaft and I was assuming we where still talkin about tailshaft and yoke. Plus I was at work dealin with a dumb supply sgt. Wasnt thinkin.

[kewljay223]

haha. Brain fart... we all been there. no prob bud.
